GLASS-FINISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 623,291, dated April 18, 1899.

Application filed naemterialssa Serial No. 699.723. (NomorlelJ To all whom it may concern.-

Be it known that I, HERMAN SOHREIBER, a resident of Dunkirk, in the county of Jay and State of Indiana, have invented a new and paratus.

The object of my invention is to provide a compact, simple,and convenient form of glassfinishing apparatus in the operation of which the articles to be finished may be handled and finished in quick succession and the work accomplished with greater uniformity and more perfectly.

To these ends my invention comprises the novel features hereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which' Figure 1 is a side view of myimproved apparatus. Fig. 2 is a view of the opposite side. Fig. 3 is a section on line 3 3, Fig. 1. Fig. 4 is an enlarged vertical section of the burner, and Fig. 5 is aplan view of the burner removed.

Like letters indicate like parts in each of the figures.

The letter (L in the drawings designates a bed or support upon which my improved finishing apparatus is mounted, and as said bed is preferably mounted on Wheels I have illustrated it as so mounted. It is thus capable of being quickly moved from one part of the factory to another.

Supported by the bed a are the uprights Z). At the upper ends of the uprights b are the brackets o c, the bracket 0 forming part of the ring (1 and having an opening through which the upright Z) passes, so that said bracket is capable of being moved up and down on said upright. The set-screw e acts to secure the bracket to said upright when it has been adjusted at the proper height. The bracket 0' has an opening through which the upright (1 passes and is also vertically adjustable on of fire-clay or other suitable refractory ma-- terial and has the neck h, which fits down Within the ring d and rests upon the flanged, while the shoulder h rests upon the flange 1 The glory-hole II has the conical opening 7L2, and at the lower or larger portion of said opening is the burner g, encircling said opening. The glory-hole is slightly recessed or grooved, as at 7L3, to receive the burner, and

said bu rneris secured therein in any suitable manner. The body of the burner g is circular in form and is provided with the apertures g. The straight extension 9 of the burner 9 projects out through an opening in the ring d, and to said extension is connected the gas-supply pipe g", by which gas is sup plied to said burner.

The walls of the glory-hole H just above the conical opening 7L2, are provided with the apertures hi by means of which the waste products of combustion escape to the space 2', formed between the glory -l1ole and the outer dome 7t. This outer dome 7t may also be formed of fire-clay, and it has the escapeflue 7a, to which a suitable chimney on may be connected.

In alinement with the opening 77, of the glory-hole H is the sleeve it, said sleeve being mounted on the bed a and around the opening a in saidbed. A vertically-movable rod 0 is contained within the sleeve m. At the upper end of said rod 0 is the socket or seat 0, adapted to receive the shank r of the former r. .The shank 4* has the annular groove 0*, which forms a seat for the entrance of the tool used for placing the shank in the socket o and removing it therefrom. The

former illustrated is one adapted to receive a glass dish r but formers of different shapes may of course be employed. At the lower end of the rod 0 is the cross-bar s, to each end of which is secured a chain 8 8?. These I right within the guide u to support the lever a at different heights, according to the position of the rod 0 with reference to said glory-hole.

\Vhile I have described only one glory-hole and its connections, one vertically-movable rod, &c. yet the drawings show all the partsin duplicate, and the apparatus is preferably constructed in this form, although it is of course apparent that the number of gloryholes may be increased, if desired.

I do not wish to limit myself to the exact construction shown, as that may be varied without affecting the scope of my-invention.

The operation of my improved glasswarefinishing apparatus is as follows: The gas is turned on at the valves of the supply-pipe, and the gas is ignited at the burners g. The products of combustion rise within the vaulted glory-hole and thoroughly heat same before they find their way out through the apertures If. The conical-shaped opening 7L2 directs the heated products toward the center of the glory-hole, where the mostintense heat is desired. lVhen the glory-hole has been properly heated, the operator, with the former r in position to receive the dish r re ceives said dish thereon in its inverted form from the boy who brings it directly from the press. The former is lifted and its shank r is placed in the socket 0 of the rod 0, said rod having been lowered by the lever 11 to the position shown in Fig. 1. Havingmounted the former carrying the dish on the rod 0, the operator grasps the lever u and raises said rod until the former passes up through the opening 7L2 into the glory-hole. The dish is then subjected to the intense heat of the glory-hole, and the edges of said dish are in the direct path of the heat as it comes from the burner. As the edge of the dish around its entire circumference is exposed tothe same heat, the finishing is uniform and perfeet, and no rotation of the rod carrying the dish is necessary. The circular burner distributes the heat evenly, so that no part is more highly heated than another.

WVhere two glory-holes are mounted on the same bed, as illustrated, the operator can arrange to have one of the rods elevated, so as to bring the dish within the glory-hole while he lowers the other rod, removes the finished dish with the former, and places another former in the socket of the lowered rod, said rod being supported by the lever to, engaging the notches in the guide a. This rod is then elevated and the other one lowered. In this manner in quick succession the dishes are finished as they are carried from the presser.

By my invention I provide a glass-finishing apparatus in which the glory-hole and the devices for introducing the articles of glassware thereto and withdrawing them therefrom are so combined as to form a simple, compact, and conveniently-handled apparatus which will give greater uniformity and a better-finished product.

That I claim as my invention, and desire to secure by Letters Patent, is-

1. In glass-finishing apparatus, the combination with a suitable support, of an upright rod on said support, a glory-hole mounted on said upright rod and vertically adjustable thereon, said glory-hole having an opening in the bottom thereof, and a vertically-movable rodin line with said opening adapted to support the article of glassware, substantially as set forth.
